The pilot flying of this aircraft was a qualified and certified pilot. Happens to be a female. So what? Females have been high-scoring aces, have saved RPT jets in distress, and also been killed by male pilots who screwed up, biggly. There have been some notable crashes where the co-pilot was female, UAL585, Colgan, USBangla, and in none of those events would gender have made any difference to the outcome. Male co-pilots and Captains have been screwing up since Wilbur and Orville were working out how to make date night work, and that seems to be the direction we intend to continue with. The DXB departure was not dependent on the gender, nor was the arrival done by a group of male pilots.
A charge of bias towards females comes from a pretty interesting place, one has to ask why they were underrepresented in the first place; that is where the bias arose. Have just completed over 150hrs with one young lady, and she exhibited the exact same weaknesses in her competency as a male compatriot who had 10 times her experience. Whatever the issues are, gender didn't enter into the issues.
